At least 15 people were wounded across the city over a seven-hour span late Friday and early Saturday morning, according to police reports, and the violence continued into Sunday.

Early Saturday morning three gang members were charged with aggravated battery and various other offenses after throwing beer bottles at an off-duty police officer.

The officer was attempting to get by them in his car as they blocked the street in front of a Pilsen bar. He identified himself as police and attempted to clear the men from the road, police said. The three then threw beer bottles at the officer.

Also on Saturday, a 22-year-old southwest suburban man was shot in the leg shortly after midnight in Joliet. The suspect pointed the gun at a crowd of people in the hallway and opened fire, shooting three times, police said. The victim was shot in the right leg.

Sunday morning, a 29-year-old man was fatally shot in the head around 12:30 a.m. as a group of about 50 adults were hanging out at a well-lit play-lot at West Side Garfield Park Elementary School, police said.

An additional six people were injured, including a teenager, in separate shootings Sunday morning on the South Side.
